Images are captured perfectly with no inherent spatial blur due to diffraction, motion blur, or camera shakes. Image sharpening can bring out hidden details and sharpen blurry images; photoshop can help to resolve specific grainy issues.

GNU Image Manipulation Program (GIMP)

GIMP is an image manipulation program that operates under Linux and most other Unix-like platforms. Although it can provide advanced features, including animation and 3D modeling, its more basic functions are manipulating individual images. GIMP sharpen image feature has three different filter tools used for sharpening: unsharp mask, smart sharpen, and gaussian blur. Each tool has its unique functions and uses depending on the type of image.

  • Unsharp Mask: Unsharp masking is a technique that increases an image edge contrast making it appear sharper or crisper than it would otherwise be if it were blurred by either camera movement when focusing or other types of degradation.
  • Smart Sharpen: Smart Sharpen enhances both textural details and edges without creating halos along with high-contrast areas, making it one of the best sharpening tools for images that have large areas of solid colour. Unlike unsharp masking, smart sharpen allows controlling the amount of sharpening applied to the image. The user can adjust this number by moving a slider back and forth between 0% and 100%.
  • Gaussian Blur: GIMP uses Gaussian blur for anti-aliasing filters, but it also serves another purpose. The noise becomes more apparent when an image is enlarged for printing, creating a speckled pattern of grey dots. To combat this issue, users can use the Gaussian blur filter to slightly blur the image to average out the brightness values in pixels that are too close to each other, making them appear more closely matched.

Steps to Sharpen Image Using GNU Image Manipulation Program (GIMP):

Step 1: Open the image in GIMP that needs to be sharpened.

Step 2: Go to Filters > Enhance > Unsharp Mask.

Step 3: Move the Radius slider (the higher it is, the more sharpened the image will be) and the Amount slider (keep this at a lower value; preferable not to go above 150%).
